RESUMEN
Molecular breast imaging (MBI) is an adjunctive screening tool that can be helpful in evaluating women with dense breasts or in high-risk patients. We present the case of a 43-year-old female who had markedly asymmetric uptake in one of her breasts on MBI study. Further evaluation with diagnostic mammogram and ultrasound did not demonstrate any suspicious findings in the affected breast. Discussion with the patient and additional clinical history revealed that the patient was exclusively breastfeeding from that side, accounting for the unilateral MBI findings.
RESUMEN
Noniatrogenically acquired foreign bodies in the nipple-areola complex or breast skin are rare and can have variable imaging features, depending on the nature of the foreign material. We present the case of a 41-year-old female who had numerous apparent round and punctate calcifications in the right periareolar breast, predominantly within the skin. The biopsy showed multiple glass shards on a background of scar tissue. Further discussion with the patient confirmed that the glass shards were acquired during a motor vehicle accident several years earlier. We also review the types of foreign body material observed in the breast, the imaging appearance of glass foreign bodies in soft tissue, and methods of removal.
RESUMEN
PURPOSE: To evaluate the impact of trimodality treatment versus monotherapy or dual therapy for radiation-associated angiosarcoma of the breast (RAASB) after prior breast cancer treatment. EXPERIMENTAL DESIGN: With Institutional Review Board approval, we identified patients diagnosed with RAASB and abstracted data on disease presentation, treatment, and oncologic outcomes. Trimodality therapy included (i) taxane induction, (ii) concurrent taxane/radiation, and then (iii) surgical resection with wide margins. RESULTS: A total of 38 patients (median age 69 years) met inclusion criteria. Sixteen received trimodality therapy and 22 monotherapy/dual therapy. Skin involvement and disease extent were similar in both groups. All trimodality patients required reconstructive procedures for wound closure/coverage, compared with 48% of monotherapy/dual therapy patients (P < 0.001). Twelve of 16 (75%) patients receiving trimodality therapy had a pathologic complete response (pCR). With median follow-up of 5.6 years, none had local recurrence, 1 patient (6%) had distant recurrence, and no patients died. Among 22 patients in the monotherapy/dual therapy group, 10 (45%) had local recurrence, 8 (36%) had distant recurrence, and 7 (32%) died of disease. Trimodality therapy demonstrated significantly better 5-year recurrence-free survival [RFS; 93.8% vs. 42.9%; P = 0.004; HR, 7.6 (95% confidence interval, CI: 1.3-44.2)]. Combining all patients with RAASB regardless of treatment, local recurrence was associated with subsequent distant recurrence (HR, 9.0; P = 0.002); distant recurrence developed in 3 of 28 (11%) patients without local recurrence compared with 6 of 10 (60%) with local recurrence. The trimodality group had more surgical complications that required reoperation or prolonged healing. CONCLUSIONS: Trimodality therapy for RAASB was more toxic but is promising, with a high rate of pCR, durable local control, and improved RFS.

Infectious diseases of the breast can demonstrate a wide variety of clinical presentations and imaging appearances. Breast abscesses are often a complication of infectious mastitis of the breast. Puerperal mastitis is the most common cause of breast abscess, typically affecting postpartum females. Often diagnosed clinically, it is usually treated with antibiotics without need for imaging. Non-puerperal mastitis is relatively uncommon and typically subareolar in location. Patients can present with asymmetric breast thickening, a palpable lump, nipple discharge, or axillary adenopathy. These presentations can mimic malignancy. Herein, this pictorial review demonstrates imaging findings of common and uncommon infectious processes of the breast and clinically important mimickers of breast infection.

Radiation-associated angiosarcoma of the breast (RAASB) is a rare and aggressive malignancy occurring after radiation therapy as part of breast cancer treatment. RAASB usually presents several years after prior radiation and typically involves the skin with or without involvement of the parenchyma. Most RAASB are detected as cutaneous changes on physical exam. Herein, we present a unique case of a clinically occult RAASB diagnosed as non-mass enhancement on annual surveillance breast MRI.
